What is Multiphase meter?

The Multiphase meter Technology is the combination of the robust concept ofVenturi and well known and unique measurement of Multi-Energy

Gamma Ray to replace conventional well testing

Features and BenefitsOperation efficiency and safety

Compact, lightweight & small footprint Limited pressure test lines Simple equipment

mobilization

Reduced crew

Short operation duration, saving rig time and reducing flaring fast rig-up and rig down clean-up optimization no stabilization time

required

On line, continuous production monitoring

No moving part (low failure probability)

Data quality & Metrological performance

Improved accuracy vs. conventional testing

High repeatability

Independent of flow regimes

Exceptional dynamic response

Flow rate measurements during all clean-up

Early water detection

Not affected by slugs, foam and emulsion

Unique hardware for heavy oil, black oil, volatile oil, gas condensate, wet gas and dry gas well testing

Reduce the Operation cost

Results

We can subtract H8 oil Q=1761.9-1580=181.9 STB/d, gas Q=163.54-142.03=21.51 MScf/d, water Q=590.86-382.01=208.85 STB/d.

BSW=590.86/(590.86+163.54)=78%
